I don’t know what a .webp file is but I don’t like it. They’re like a filthy prank version of the image/gif you’re looking for. They make you jump through all these hoops to find the original versions of the files that you can actually do anything with.
I think so, but I’m no expert on the details of legal ownership.
@Dark_Arc@lemmy.world added a good comment here that explains the royalty free licensing.
Thanks!
